' it known that I, REiiIemsDAxToxio,

a subject 'of the King of Italy, residing at in the line of the wavesfrom the reflector I 2, are directed to the coherer i. Under these Capistrano Aquila, Abruz zi, Italy, have in? vented tzertain new and useful Improvements in Reflectors for \Vireless 'Ielegi-apliy, of which the following is'a, specification..-

.This invention relates generally to wirelesstelegraphy, and particularly, to a system designed tobe employed by vessels to .prevent collisions in foggy or heavy Weather.

The present invention embodies in its con ception the well-known Marconi system of wireless ftelegraphy, in all its details, andires no detailed description of" therefore req its j' application."

, The object' ofthe present invention is so i to mount the. reflectors, that they will al-- ways maintain a horizontal plane irrespec-, tive of the anglelof tli'e' deck of the vessel, reflection of signals from a vessel-within the wave lines.

- With the above-andother. objects in view,;

as' will appear as the nature of the invention is better understood, the same consists,

In installing the invention, two reflectors l and 2 are employed; which, as shown-inf Figs. 2 and 3, are semicircular in cross-section, althoughi'the ordinary form of paraboliforin reflector may be substituted, if preferred, or found of advanta e;

port. and the reflector 2 projects in aforward direction, the electric waves produced by the oscillator 3, and the reflector 1', if itconditions, the coherer establishes a circuit with the battery 5,'in which circuit is com prised a relay 6, the object of which is to complete the othericircuit with the battery 7. In the circuit of the battery 7 is included a bell 8 and a. de-cohering .tapper 9 of the,

usual or any preferred construction;

The above description is general in charconi system. i 1

Under, existing conditions,

of aMarcoiii system onsliipboard are practically limited to atmospheric ;coiiditions acter,,andrefers, as above stated, to the Mar 1 that is t0'; Say if'the weather be stormy the reflectors, owing to an absence of any means for maintaining them ina. plane parallel the reflectors with-the horizon-is absent. As will beuob:

vious,.to secure effective results,iit is necesw."

"the weather, the reflectors should maintain a condition of. stable equilibrium,. rrespec sary that whatever may be the conditions of .tive-v of climatic conditions, thus to insure the positive coaction between the two re- 'flectors;'

The reflectors may be of semisplierical form or of paraboliforin and may be'of any material adapted to the purpose.

' The apparatus comprises two semi-spherical bearings 10 that are designed to encircle partially a ball 11 carried by the shank 12 of the reflector 13 with which is combined the coherer 4 .of the usual or any preferredconstruction. The bearings 10 are counter-. parts, and each is provided with an elon'- gated portion 14 arranged to fit within-a socket 15in the upper end of a'base 16, the lower ends of which'are substantially bolted to base 17. The members of the bearings 10 are held assembled by abolt'18, anut 19 bled. v

In operation, the counterpoise 20 will bolt1 8. and n'ut19, the response of the reflectorto the undulations of wave motions serving to hold the parts properly asseni-f serve to maintain the focal; axis of the "re-' flectorparallel with thehorizon irrespective of the coherer, and by the provision of the 95.

will be delicately responsive to all condis tionsa In Fig. 1 of the drawings, the transmitter and receiver, installed on a ship, are shown;

in combination. I In the part of the appara fit tus comprising the transmitter there are three electric circuits. The first is formed between the battery 7 and the motor 22,

and is closed by loweringthe key 25. The

second circuit is derived from the points A- and Band comprises the primary P of in-- duction coil 21. This latter circuit is closed alternately by the eccentric 23, fixed to the shaft of the motor 22 as the eccentric presses againstthe contact 24 and causes it to engage the binding post 25. The third electric circuit is derived from the first at M and the second at N. This third circuit includes the signal bell 8 and'the decohering tapper 9, and is dependent for its closing upon the relay 6. In the part of the apparatus comprising the receiver there is only one electric circuit, which includes the battery 5, the

.icoherer & and the relay 6. The electric circuits being thus described, the functions of the-transmitter and receiver will readily be understood. As regards the former when the key 25 is lowered, a circuit is established between the batter '7 and the motor.

projected forward by the reflector of an othership fall upon the reflector 1, the cothe present invention, the reflectors 1 and 2 are situated onthe'bridge of the ship, one

to the right and the other to the left.

The signaling action'of the present inven tion is'possible onl when the. apparatus as described is insta led ontwo vessels that threaten to collide, In this may, Waves are projected directly from the transmitter of one ship to the, receiver of the other and there is thus a mutual interchange of signals.

I claim. A -wireless. signaling system for vessels embodying spaced supports at diflerent points upon thevessel, a slotted bearin socket upon each support, a ball journale in each s0cket,'a stem carried by each ball and projecting through and movable in the slots ineach socket, a reflector upon onefend of each stem, a counterbalancing weight upon the opposite end of each stem, and wireless signaling means including a transmitter associated with one reflector and a receiver associated with the other reflector.

In testimony whereof I aflix my signature presence of two witnesses.
